Answer: To determine the mole ratio
Explanation:
A balanced chemical equation is needed ,because it helps to determine the mole ratio of acid and base.
The mole ratio ensures that the number of moles of H+ provided by the acid is equal to number of moles of OH- ion provided by the base, For neutralization to occur, this must be the case.
To answer this question, you need to know how to convert milliliters into liter then into a gallon. In this question, you are given the gasoline density (0.737g/ml) and the volume (12.8gallon). The information is enough to determine the gas weight. The calculation would be:
Gas weight= density * volume
Gas weight= 0.737g/ml * 12.8 gal * 3.78L/gal * 1000ml/L= 35659.008 grams
Answer:The maximum kinetic energy KEe of ejected electrons (photoelectrons) is given by KEe=hf−BE KE e = h f − BE , where hf is the photon energy and BE is the binding energy (or work function) of the electron to the particular material.
